UNITED STATES PATENT OFFICE,

JAMES WEATHERS, OF INDIANAPOLIS, INDIANA.

SASH-BALANC E.

SPBCIFICATION formig part of Letters Patent No. 334,628, dated January 19, 1886.

Application filed October 29, 1885. Serial No. 181,313. (No model.)

To all whom it may concern:

Be it known that I, J AMES VVEATHERS, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, haveinvented certain new and useful Improvements in Windows, of which the following is a specification,reference being had therein to the accompanying drawings.

My invention relates to improvenents in windows or Vertically-moving doors and shutters, and is designed to produce a device whereby the sashes (in windows) will move automatically to what is commonly termed an open position, they being nornally retained in a closed position.

Being aware of the' disadvantages attending the use of unguided springs that act to move the sash by their contractile force, I design to obviate the same by this invention, which consists in utilizi ng the expansive force of a coil spring guided by rods in the easing in a manner hereinafter set forth.

I accomplish two objects not attained by the devices referred to. First, by utilizing the expansive force of the spring the Stretching and consequent weakening of the same is obviated, and, second, by using guiding-rods, around which the spring is coiled, the sashes are guided and the said spring prevented from crimping when contracted.

In the drawings, Figure 1 represents a front view of a window with parts broken away and sectioned; Fig. 2, a cross-section of one side of the easing and sashes, and Fig. 3 a detail of a bearing plate located on the edge of the sash.

In the said drawings the upper and lower sashes are lettered A and B, rcspectively, and each has on each side a longitudinal groove, C. Resting centrally in the spaces between the guide-strips D are rods E, secured in the top and botton of frame and surrounded by the spiral springs F. On top the sashes, at each side, are firmly secured the slotted plates G, the said slots being coincident with the ends of the grooves C, and of sufficient size to admit the passage of the rods E, but not of the springs F. Each sash is provided'with a hook or catch, H, which engages with a stop on the easing or frame. The springs F are of sufficient length and strength to sustain the sash at the top of the easing. The upper sash, A, is normally retained in the said position, and when lowered is held by the catch H thereon, on releasing which the springs immediately raise the said sash to its proper or elevated position. sash, B, the springs are normally conpressed, and the catch holds the said sash in place. XVhen released, the sash will automatically rise. The plates G serve to strengthen the sash, to keep it running smoothly on the rods, and to form a bearing for the springs.

I wish to be distinctly understood as not broadly claiming springs which act by contraction'in connection with window-sushes to operate the same.

I am also aware that it is not new to bore holes in the edges of the sash and insert springs in said recesses for the purpose of facilitating the operation of the sash.

It will be seen from the forcgoing that the essential feature of this invention consists in providing the sash with longitudinal grooves for' the reception of rigidly-secured rods, and coiled springs surrounding said rod and acting by their extensible force.

This invention, as before stated, is equally applicable to doors. shutters, or the like when they are made to slide and are not hinged.

I claim- 1. Combined with a sash longitudinally grooved on each side, fixed rods extending the length of the frame and resting in said grooves, and springs surrounding said rods and acting on said sash by their extensile force, substantially as Specified.

2. Combined with a sash longitudinally grooved on the edges, fixed rods extending the length of the window-frame and resting in said grooves, springs surrounding said rods and normally contained within said grooves, and slotted plates on the sash coincident with said grooves and forming bearings for said springs, substantially as Specified.

In testimony whereof I affix my Signature in presence of two witnesses.

JAMES YVEATHERS.
